People are crying. It's post after post of bitching and complaining. It's not discussing. It's "You screwed me Apple and I'm mad." People going on about how they won't be giving them their dollars. It's a whole "I'm taking my ball and going home." attitude. The old graphics option was hardly any better than the integrated graphics. This integrated graphics should be slightly better than it.
Remember, Apple makes this machine to sell to those looking for web browsing, email, word processing and maybe light game. It's not meant to be a gaming machine. For 99% of those that consider the Mac mini, it's more than enough as it stands. Those looking to game should look elsewhere as that has never been what this machine was about.
To the contrary, many people are making valid points germane to the thread.
As these are intended updates, there's no obvious good reason to not clearly improve the HD 6630M Mini in all departments, even if the HD 4000 makes sense in the base model.
FWIW, I have the HD 6630 model & it's no slouch for anything but fairly modern, graphically-intensive games.
As I say elsewhere, IMO, for the price being asked, I'm not surprised that many people might have expected similar updates generally, but at least to have a definite improvement on the previous, higher-end Mini's HD 6630M discrete card.
Hoping for another, slightly better discrete card in the higher-end Mini, whilst also doubling the previous VRAM to 512, isn't really expecting a lot or something unreasonable here.
I imagine most of those complaining now might have been pacified.
As it is, only Apple in the entire computer hardware industry would effectively give you a slight graphical downgrade in the higher-end Mini.
FWIW, I like using Macs. They're excellent computers in many respects, but find it disappointing that greed seems to have no bounds with this company.
